To support DTNA’s growth and the addition of approximately 400 new positions in Portland, this 268,000 SF state-of-the-art building supports innovation with modern, collaborative work spaces and conference rooms with sophisticated A/V systems. The office spaces have free access raised floors to provide low voltage and floor plugs. The project achieved LEED Platinum, with features that include radiant heating/cooling, PV array, and a “Living Wall,” an interior vertical wall covered in plants. Hoffman recycled over 95% of demolished materials.

Hoffman self-performed all structural concrete work on the project. To meet a fast-track schedule, we poured a new structural floor plate every five days. With three plates per level, the building rose one story every 15 days. The new headquarters also includes a 1,300-stall, cast-in-place concrete parking garage, which features a solar array on the roof that helps to power the neighboring headquarters building, plus electric charging stations.
